DD is in year 1. There are approximately 45 pupils in her year (across 2 forms), all of whom she knows. Since the beginning of the year, most parties have been whole-class invites (though not whole-year), although there has been at least one exception where a girl invited 8 or so girls to her party.
DD wants to invite girls from both classes, as well as some outside friends, to her party. So we'd be inviting 6 girls from her class, 4 from the other class, and about 10 other kids. Some of the girls who would not be receiving an invite are girls whose birthdays DD attended.
So, fire away. Is it okay not to invite the whole class? AIBU not to invite girls who did invite DD to their own parties?
